Engine issues related to valve guide wear are common. Oil consumption, smoking at first startup, and valve train noise are all symptomatic of loose guides and worn valve stems. The valve train is complex and should be thoroughly inspected if a problem arises.

Creaking noises while driving over bumps and when cornering may be difficult to diagnose, but are usually caused by the windshield at the body/seal area. The latest version seal and/or lubricant can solve the problem.
